Customer Imperatives Today• Cost Effectiveness/ROI
– Ability to Backup and Archive data in a heterogeneous environment with a single LAN-free solution
• Deliver on SLA requirements– OpenVMS issues
• Not always feasible to backup across the network– Multiple TB’s stored– Mission Critical Applications– OpenVMS Clusters are common– Oracle and Oracle RDB are frequently used
• Resources focused on value-added applications• Improve access and retrieval of corporate data• Systems and software that are aligned to changes in
the business

Gartner’s view of LEGATO
LEGATO’s History with HP starts with Digital• Digital OEM’d NetWorker for Ultrix; later OSF/1 (Digital/Tru64
Unix) and Windows NT on Alpha• Digital outsourced development of OpenVMS client to
Wumpusware• Digital Outsourcing selected NetWorker as default backup tool• On acquisition of Digital, Compaq changed software strategy
and returned NetWorker source to LEGATO – Compaq continued to provide 1st & 2nd Level Technical Support– LEGATO NetWorker Single Server ships with Tru64 UNIX
• Outsourcing agreement expanded to include right to resell LEGATO’s full product suite
• Consulting and integration services agreement to design and implement Legato solutions
• HP can resell LEGATO products today

Value Proposition
• NetWorker for OpenVMS– Reduces TCO by:
• Including OpenVMS systems, and clusters, in heterogeneous backup solutions
• Reducing training needs, and administration costs, by providing a cross-platform GUI and command line
• Reduce load on valuable staff– Move tasks to Operations– Consistent policies, no matter the platform
– Improving ROI by • Sharing tape devices, media, and libraries with UNIX and
Windows systems• Delivers LAN free backup and archiving to direct, or fibre
channel, attached tape or disk

Pool
1. Initial backup operations use intermediate high speed disk devices2. Interim recovery operations occur at disk speeds -- no manual intervention3. When devices reach customer specified thresholds, NetWorker can
automatically stage backup data to removable tape media or libraries (freeing up disk capacity)
4. Single Step recovery

• Supports OpenVMS data being stored in heterogeneous fibre-based SAN environments, including library sharing and tape drive sharing – an industry first!
• Protects OpenVMS servers to locally attached tape libraries reducing network traffic and improving backup and recovery performance (storage node only)
• Allows for a centrally managed backup and recovery solution for OpenVMS systems that exist within a mixed UNIX, Windows, Netware and Linux environment
• Supports OpenVMS clients running in an OpenVMS cluster
• At least match OpenVMS Backup performance

Oracle Support on OpenVMS
• In Beta now, Release in December• Supports SBT (RMAN) API V2.0
– Oracle 8i, 9i and 10i– Rdb 7.1.2.1.0
• Worked closely with Rdb engineering team• LIBRARIAN qualifier supported
– Database backup and restore– Journal backup and recovery
• requires a patch from Rdb.
IT-Symposium 2004
www.decus.de 21
Rdb Support• Use the /LIBRARIAN qualifier with RMU
– Device, directory, file type are ignored• Specify reader and writer threads in
commands, like:
• Backup save set managed by NetWorker• Restore is just as you would expect
$ RMU /BACKUP /LIBRARIAN /LOG –_$ rdb-root-file rmu-backup-file
$ RMU /RESTORE /NOCDD /LIBRARIAN /LOG rmu-backup-file
Multi-threaded Backup Supported• Specify reader and writer threads in commands, like:
• Results in three backup files (managed by NetWorker)
• On restore, if reader threads don’t match writer threads use /VOLUMES
$ RMU /BACKUP /LIBRARIAN = (WRITER_THREADS = 3)/LOG –_$ rdb-root-file rmu-backup-file
RMU-BACKUP-FILE.RBFRMU-BACKUP-FILE02.RBFRMU-BACKUP-FILE03.RBF
$ RMU /RESTORE /LIBRARIAN=(READER_THREADS = 2) –_$ /VOLUMES=3 rmu-backup-file
IT-Symposium 2004
www.decus.de 22
Parallel Process Backups with Rdb• Multiple processes distribute backup
processing across SMP processors, cluster nodes
• Can use both parallel processes and threads
• These commands write to 9 save sessions• SQL/Services required for parallel backups
$ RMU /BACKUP /PARALLEL = EXECUTOR = 3 -_$ /LIBRARIAN = WRITER_THREADS = 3 –_$ /LOG -_$ rdb-root-file rmu-backup-file
Backup Plans Supported• Generate a backup plan then edit, execute:
$ RMU /BACKUP /PARALLEL = EXECUTOR = 3 _$ /LIBRARIAN = WRITER_THREADS = 3 –_$ /LIST_PLAN = parallel_backup.plan –_$ /NOEXECUTE /LOG -_$ rdb-root-file rmu-backup-file$$ EDIT parallel_backup.plan$$ RMU /BACKUP /PLAN parallel_backup.plan
IT-Symposium 2004
www.decus.de 23
Restoring using Rdb
• Use the same plan file to restore the database
• Parallel restore still not supported• Limit restore threads like this:
$ RMU /RESTORE_$ /LIBRARIAN = (READER_THREADS = 3, –_$ PLAN_FILE = parallel_backup.plan) –_$ /LOG -_$ rmu-backup-file
